IMPROVEMENT IN TIRE-SETTING- MACHINES.

The Schedule referred to in these Letters Patent and making part of the same.

We, Aunnnw Suoennn and HENRY .A. ADAMS, of Sandwich, in the county of De Kalb and State of Illinois, have invented a new and useful Improve ment in Tire-Setting Machines, of which the followmg 18 a specification, reference being had to the accompanying drawings, which form a partthereof.

The Object and Nature of our Invention;

'wheel than when the tire is suflieiently heated to conform to the irregularities of the circumference of the wheel, and we can set the tires much quicker.

The nature of our invention, to accomplish the above objects, consists in the clamps for clamping or clasping the tread of the wheel, and also in the combination of leversfor operating said clamps, and also the combination with the clamps of the guides and supports, as hereafter more fully described.

Description of the Drawings. Figure 1 represents a top or plan view of our ma chine, and fi Figure 2, a vertical sectional view at the line at x in General Description.

The same letters of reference refer to the corresponding parts in the difierent figures.

A represents the frame or bed-piece of the machine supported upon legs B.

G is a circular piece rigidly attached to the frame A, and

. D are guides extending through the circular piece 0, forming a part of it, to make the. circle continuous.

E are clamps for clamping the wheel, as hereafter described, and weusually make them in segments, as shown.

When in position in the machine for use, they rest upon the circular piece 0 and guides D, the piece F resting in the groove H.

It will be observed that the piece F is attached to the under side of the clamps, or it may be made a part of the clamps, just wide enough to play in the grooves H, and guide the clamps, when operated, toward the center of the wheel.

I is a square-shoulder on the clamps E which clasp over the lower; edge of the felly J of the wheel, so that wheuthe clamps are drawn toward the center of the machine, as hereafter described, the pressure is thrown upon the felly of the wheel and all the joints I of the wheel are closed and the wheel compressed to the circumference necessary to receive the tire and give to the wheel the proper crown or disk. The tire is then placed upon the wheel and forced upon the fell y as far as the shoulders 'I of the clamps E. p

K are rods connecting each of the clamps tothe lever L, which has its fulcrum ou'the center pin 0.

The rods K are so connected with the lever L that when it is vibrated it moves all the clamps E toward the center of the machine, and all the s amedistance, so that the pressure is uniform around the entire circumferencetof the wheel. I I

P is also a lever with its fulcrum at Q, and its short end is attached to the lever L.

R is a pawl which falls in the cogs S and holds the lever in position as the wheel is clamped.

'1 are clasps attached to the machine in suitable places'to be turned over the tire and hold it upon the wheel on one side while it is being drawn upon the wheelou the otherside.

To operate our machine, the operator throws back the lever P, which, through the action of the lever L and rods K, slides the clamps E back in the grooves I' H, and they are ready to receive a wheel, as shown in fig. 2.

The operator then moves the lever'P, and through the lever L and rods K, moves the clamps toward the center of the wheel, the shoulders I clasping the fell y of the wheel and compressing it together.

The pawl It holds the lever P at any desired posit-ion, so that the operator, when he has clamped the wheel, can then take the tire and place it npon'the wheel, and if it goes a little tight so that it is neces%- sary to work down one side at] a time, the clasps T are turned over the side that is worked down to hold it on the wheel whilethe operator is working down the tire on the other side-of the wheel.

When the tire is put upon the wheel down to the shoulders I, the wheel is taken from the machine, turned over, and placed upon an. anvil or other suitable place, and the felly forced entirely and evenly within the tire.

Tires can be set rapidly with our machine.

It will'be observed that clamps of various shapes could be used, and also that it would not be necessary to have a continuous shoulder, I, as various devices for clamping the wheel could be used.

G lmlm s.

We claim--- 1. lhe clamp; ;E for the purpose of claspiug the felly of a wheel and clamping the wheel, when con- Shdwn;

2. The levers P and L,"the connecting-rods K, and

clamps for clamping the wheel, when constricted and operating substantially as shown.

3. The clamps .E and guides D iu a. tire-setting structed and operatingsubstantially as specified and machine, for guiding the for the purposes specified I Witnesses:
